Find the value of x. Then find the angle measures of the polygon.

Answer:
X=140/3
Step-by-step explanation:
180-40=140, 140 divided by 3 is 140/3, so 40+3x140/3=180
Answer: x = 35
Final answer: 40, 105, 35.
Answer: x = 35
So, it would be 40, 3(35), and 35.
Final answer: 40, 105, 35.
First, we know that sum of angle measure 180.
So, algebraically, we can put out this equation.
40 + 3x + x = 180
Now we solve
Step-by-step explanation:
Given: 40+ 3x + x = 180
The whole goal is to isolate x. Remember DCMAM: Distribute, combine, move variable to one side to another, add/subtract, divide/multiply
There is no distribution, so move on.
We do have to combine 3x with x
40 + 4x = 180.
Now move 40 to the right side.
40 + 4x = 180
-40 -40
4x = 140
Now divide 140 by four
4x/4 = 140/4
x = 35
So, it would be 40, 3(35), and 35.
Final answer: 40, 105, 35.
Hope this helps.
